八十年代,世界非金属矿使用范围扩大,需求量猛增。非金属矿产值超过金属矿产值的50—60％。非金属矿业的高速发展,吸引了大量科技工作者。各国都加强了非金属矿产的地质调查和岩石矿物的实验研究。例如,苏联科学院在1979年9月的一项决议中就指出“非金属矿新类型的研究,是现代地质学最重要的方向之一,要加强非金属矿物
In the 1980s, the use of the world’s non-metallic mines expanded and the demand soared. Non-metallic mineral value of more than 50-60% of the value of mineral metal. The rapid development of non-metallic mining has attracted a large number of scientists and technicians. All countries have strengthened the geological investigation of non-metallic minerals and experimental study of rock minerals. For example, in a resolution of September 1979, the Soviet Academy of Sciences pointed out that "the study of new types of non-metallic minerals is one of the most important directions in modern geology. It is necessary to strengthen the non-metallic minerals
